Around day 21 of my partner Marie's cycle, the fridge rearranges itself. The salad greens get pushed to the back. Dark chocolate appears on the counter. A sweet potato shows up on the shopping list circled twice. She's been tracking this pattern long enough to know it's not random, and after two years of building bauchgefühl.app together, I've learned enough about the science to understand why.
I'm Josef. I handle the research and recipe side of things at bauchgefühl. This post is about what to eat when PMS hits, what to limit, and five recipes that actually help. No "just drink more water" advice. No guilt trips about the biscuits.
What PMS Actually Is (Quickly)
PMS, premenstrual syndrome, shows up in the late luteal phase, usually the week or so before your period starts. Progesterone and estrogen are both dropping. Serotonin tends to follow them down. The result is a collection of symptoms that roughly 75% of menstruating women experience to some degree: bloating, cramps, mood swings, fatigue, headaches, breast tenderness, irritability, and cravings.
The severity varies enormously. Some women barely notice. Others lose days. If symptoms are severe enough to interfere with daily life, that may be PMDD (premenstrual dysphoric disorder), which is a clinical diagnosis and needs professional support, not a blog post.
For the standard-issue PMS most people deal with, food is one of the most practical levers you can pull. The NHS overview of PMS covers the basics well, and a PubMed review on diet and PMS found meaningful links between dietary patterns and symptom severity.
Foods That Help PMS
These aren't miracle cures. They're foods that supply nutrients your body runs low on in the late luteal phase, and that have reasonable research behind them.
Magnesium-rich foods. Magnesium is involved in over 300 enzymatic reactions, including muscle relaxation and serotonin production. Low magnesium correlates with worse PMS. Good sources: dark chocolate (70%+), pumpkin seeds, almonds, cashews, spinach, Swiss chard, black beans.
Omega-3 fatty acids. Anti-inflammatory and potentially helpful for cramps and mood. A PubMed meta-analysis on omega-3 and premenstrual symptoms showed reduced symptom intensity with regular omega-3 intake. Sources: fatty fish (salmon, sardines, mackerel), walnuts, flaxseed, chia seeds.
B vitamins, especially B6. B6 supports the production of serotonin and dopamine. Research suggests it can help with mood-related PMS symptoms at moderate doses. Sources: chicken, turkey, salmon, chickpeas, bananas, potatoes.
Complex carbohydrates. They support serotonin synthesis and provide steady energy. Sweet potatoes, oats, brown rice, quinoa, root vegetables, legumes. Pair them with protein and fat to keep blood sugar stable.
Calcium and vitamin D. A Harvard-affiliated study found that women with higher calcium intake had fewer PMS symptoms. Dairy (if you tolerate it), fortified plant milks, sardines with bones, broccoli, and almonds are good sources.
Iron-rich foods. Especially relevant if your periods are heavy and you're heading into one. Lentils, red meat, dark leafy greens, tofu. Pairing iron with vitamin C (a squeeze of lemon, some bell pepper) improves absorption.
Potassium-rich foods. For bloating and water retention: bananas, avocado, sweet potatoes, white beans, spinach.
Foods to Limit (Not Ban)
I'm not going to tell you to never eat these. The last thing you need during PMS is someone taking away things you enjoy. But these consistently make symptoms worse for most women, so being aware of the pattern is useful.
Excess added sugar. A spike-and-crash cycle on top of already unstable blood sugar is not your friend. Swap the milk chocolate bar for a couple of squares of 70%+ dark chocolate and see if that changes anything.
Alcohol. Disrupts sleep, worsens mood instability, dehydrates you, and forces your liver to prioritise alcohol over hormone metabolism. Even moderate drinking in the PMS window tends to amplify symptoms. I've seen Marie's sleep data confirm this repeatedly.
High-sodium processed foods. Salt isn't evil, but the quantities in crisps, ready meals, and fast food can tip the bloating scale noticeably. Cooking at home and salting to taste is usually enough to keep things in check.
Caffeine in excess. One or two cups of coffee are fine for most people. Four cups plus an energy drink will make anxiety, breast tenderness, and sleep quality worse. Green tea is a decent swap for the afternoon cup.
5 PMS-Friendly Recipes
These recipes focus on the nutrients that matter most: magnesium, omega-3s, B vitamins, complex carbs, and potassium. They're simple, they use ingredients you can find anywhere, and they taste good enough that you'd make them even when PMS isn't a factor.
1. Golden Sweet Potato and Lentil Soup
This is the recipe Marie asks for most often in the last week of her cycle. Sweet potato for complex carbs and potassium. Lentils for B vitamins, iron, and protein. Turmeric and ginger for their anti-inflammatory properties. The pumpkin seeds on top add magnesium.
Golden Sweet Potato and Lentil Soup
Ingredients
- 2 medium sweet potatoes, peeled and cubed
- 150 g red lentils, rinsed
- 1 small onion, diced
- 2 cloves garlic, minced

- 1 tbsp olive oil
- Salt and pepper to taste
- Handful of pumpkin seeds for topping
Instructions
- 1Heat olive oil in a large pot over medium heat. Sauté the onion for 3 minutes until soft.
- 2Add garlic, ginger, and turmeric. Stir for 1 minute.
- 3Add sweet potatoes, lentils, and vegetable broth. Bring to a boil.
- 4Reduce heat and simmer for 20 minutes until lentils and sweet potatoes are tender.
- 5Blend until smooth (or leave partly chunky). Season with salt and pepper.
- 6Serve topped with pumpkin seeds.
2. Salmon and Avocado Rice Bowl
Omega-3s from the salmon, potassium and healthy fats from the avocado, steady energy from brown rice, and a hit of plant protein from edamame. This one comes together fast on a weeknight.
Salmon and Avocado Rice Bowl
Ingredients
- 2 salmon fillets (about 150 g each)
- 200 g brown rice
- 1 ripe avocado, sliced
- 100 g edamame beans

- 2Season salmon with a pinch of salt and pepper. Pan-fry skin-side down in a hot pan with a little olive oil for 4 minutes, flip, and cook 3 minutes more.
- 3Toss edamame with sesame oil and soy sauce.
- 4Divide rice into bowls. Top with flaked salmon, avocado slices, edamame, and cucumber.
- 5Drizzle with lime juice and sprinkle sesame seeds on top.
3. Dark Chocolate and Almond Energy Bites
Magnesium from the cacao and almond butter, fibre from the oats and flaxseed, and enough sweetness to kill a craving without sending your blood sugar into orbit. I make a batch every few weeks and keep them in the fridge.
Dark Chocolate and Almond Energy Bites
Ingredients
- 100 g rolled oats
- 80 g almond butter
- 2 tbsp raw cacao powder
- 2 tbsp honey or maple syrup
- 30 g dark chocolate chips (70%+)
- 2 tbsp ground flaxseed
- Pinch of sea salt
Instructions
- 1Combine oats, cacao powder, ground flaxseed, and salt in a bowl.
- 2Add almond butter and honey. Mix until everything holds together.
- 3Fold in dark chocolate chips.
- 4Roll into 12 small balls. Place on a lined tray.
- 5Refrigerate for at least 30 minutes before eating. Store in the fridge for up to 5 days.
They keep for 5 days in the fridge, though they rarely last that long.
4. Chickpea and Spinach Curry
B vitamins from the chickpeas, iron and folate from the spinach, anti-inflammatory compounds from the spices, and the coconut milk adds a richness that makes this feel indulgent. Comfort food that happens to be good for you.
Chickpea and Spinach Curry
Ingredients
- 1 can (400 g) chickpeas, drained and rinsed
- 200 g fresh spinach
- 1 can (400 ml) coconut milk
- 1 small onion, diced

- 3Pour in coconut milk and bring to a gentle simmer.
- 4Add chickpeas and cook for 10 minutes.
- 5Stir in spinach and cook for 2 more minutes until wilted. Season with salt.
- 6Serve over brown rice or quinoa.
5. Banana Oat Pancakes with Walnuts
B6 from the bananas, complex carbs from the oats, omega-3s and magnesium from the walnuts, and protein from the eggs. These are three ingredients at their core and take less than 20 minutes from bowl to plate. Good for a weekend breakfast or a 4 p.m. "I need something warm and sweet" moment.
Banana Oat Pancakes with Walnuts
Ingredients
- 2 ripe bananas, mashed
- 2 eggs
- 80 g rolled oats
- 1 tsp cinnamon
- 1 tbsp coconut oil for the pan
- Handful of walnuts, roughly chopped
- Optional: a drizzle of honey or a dollop of Greek yogurt
Instructions
- 1Blend or mash the bananas until smooth. Beat in the eggs.
- 2Stir in the oats and cinnamon. Let the batter rest for 5 minutes.
- 3Heat coconut oil in a non-stick pan over medium heat.
- 4Pour small rounds of batter (about 2 tbsp each). Cook for 2 minutes until bubbles form, then flip and cook 1 more minute.
- 5Top with chopped walnuts and serve with yogurt or a small drizzle of honey.
Building a PMS Week Meal Pattern
You don't need a rigid plan. But if you're looking for a framework, here's roughly how I'd structure a PMS week based on what we know about nutrient needs:
Breakfast: something with complex carbs, protein, and magnesium. The banana oat pancakes, or porridge with nut butter and seeds, or eggs on sourdough with avocado.
Lunch: a bowl or salad with protein, complex carbs, and greens. The salmon rice bowl, or a big chickpea salad with leafy greens and roasted vegetables.
Snack: the energy bites, a handful of nuts, an apple with almond butter, or a small piece of dark chocolate. Something that addresses the craving without creating a blood sugar rollercoaster.
Dinner: the sweet potato soup, the chickpea curry, or grilled fish with roasted root vegetables and brown rice. Warm, filling, nutrient-dense.
The luteal phase foods post covers the broader nutritional strategy for the second half of the cycle, and the PMS bloating foods guide zooms in specifically on water retention if that's your biggest complaint.
Frequently Asked Questions
How far in advance should I start eating differently for PMS?
Most women notice symptoms in the last 5 to 7 days before their period, but the hormonal shifts start at ovulation. Eating well throughout the entire luteal phase (days 15 to 28) builds a nutritional buffer. You don't have to wait until you feel terrible to start eating these foods. By then, you're already behind.
Can diet alone fix PMS?
Diet is one piece of a larger picture that includes sleep, stress management, movement, and sometimes supplementation. For mild to moderate PMS, food changes can make a noticeable difference within two or three cycles. For severe symptoms, please talk to a healthcare provider. Diet helps, but it's not a substitute for medical care when you need it.
Are supplements better than food for PMS?
Food is always the foundation. That said, magnesium glycinate (200 to 400 mg) and vitamin B6 (up to 100 mg per day) have research behind them for PMS. The NHS vitamins and minerals guide is a sensible starting point. Don't megadose anything without professional guidance.
Why do I crave junk food before my period?
Dropping serotonin and progesterone, combined with increased calorie needs, create a perfect storm of cravings. Your body wants quick energy and mood-boosting foods. The craving itself is real and valid. The trick is redirecting it toward foods that actually help: dark chocolate instead of milk chocolate, the energy bites instead of a packet of biscuits, banana pancakes instead of nothing-until-I-snap-and-eat-everything.
